Effects of upper limb vibratory stimulation training on motor symptoms in Parkinson's disease: an observational study.

OBJECTIVES: Parkinson's disease is characterized by motor and non-motor symptoms. Tremor is one of the motor symptoms that can affect manual skills and have an impact on daily activities. The aim of the current study is to investigate the effect of upper limb training provided by a specific vibratory device (Armshake®, Move It GmbH - Bochum, Germany) on tremor and motor functionality in patients with Parkinson's disease. Furthermore, the training effect on global cognitive functioning is assessed. DESIGN: An uncontrolled before-after clinical trial. PATIENTS: Individuals with diagnosis of Parkinson's disease, motor upper limbs deficits, and absence of dementia. METHODS: Participants underwent a 3-week programme (3 times a week) and was evaluated before, after, and at 1 month follow-up by motor (Fahn Tolosa Marin Tremor Rating Scale, Unified Parkinson's Disease Rating Scale - part III, Purdue Pegboard Test, Disability of the Arm, Shoulder and Hand Questionnaire) and cognitive (Montreal Cognitive Assessment) scales. RESULTS: Twenty subjects are included. After treatment a statistically significant improvement in tremor, manual dexterity and activities of daily living was found. The data indicated no effects on global cognitive functioning. CONCLUSION: These findings suggest positive effects of vibratory stimulation training on upper limb motor symptoms in Parkinson's disease.

Ewing's sarcoma in a young man mimicking lateral elbow pain: A case report with 2 years follow-up.

BACKGROUND AND PURPOSE: Lateral elbow pain represents a common musculoskeletal disorder, mostly non-specific and benign. In rare cases, it can be the first symptom of a severe disease such as Ewing's sarcoma (ES). ES is the second most common primary malignant bone tumor in the young population, with a high probability of an unfavourable prognosis. CASE PRESENTATION: This case report presents the history of a young man presenting to the physical therapist with a diagnosis of "epicondylitis" in the right elbow, which was later revealed to be an aggressive ES of the ulna. Findings raising clinical doubts were (a) constant pain even at night and not dependent on load, (b) significant loss of function, (c) patient's young age, and (d) a palpable mass in the elbow. RESULTS: After diagnosis, the patient received medical (chemotherapy, radiotherapy and surgery) and a rehabilitation program. After treatment, the patient improved elbow function, decreased disability and returned to social participation, maintaining positive outcomes at the 2-year follow-up. DISCUSSION: In summary, this case report emphasizes the importance of differential diagnosis and screening for referral of red flags in physical therapy. Moreover, it describes the rehabilitation of a patient with ES, enriching the scientific literature in the field.

A scoping review of scientific concepts concerning motor recovery after stroke as employed in clinical trials.

The scientific literature on poststroke rehabilitation is remarkably vast. Over the last decades, dozens of rehabilitation approaches have been investigated. However, sometimes it is challenging to trace new experimental interventions back to some of the known models of motor control and sensorimotor learning. This scoping review aimed to investigate motor control models' diffusion among the literature on motor recovery after stroke. We performed a literature search on Medline, Cochrane, Web of Science, Embase, and Scopus databases. The last search was conducted in September 2023. This scoping review included full-text articles published in English in peer-reviewed journals that provided rehabilitation interventions based on motor control or motor learning frameworks for at least one individual with stroke. For each study, we identified the theoretical framework the authors used to design the experimental treatment. To this aim, we used a previously proposed classification of the known models of motor control, dividing them into the following categories: neuroanatomy, robotics, self-organization, and ecological context. In total, 2,185 studies were originally considered in this scoping review. After the screening process, we included and analyzed 45 studies: 20 studies were randomized controlled trials, 12 were case series, 4 were case reports, 8 were observational longitudinal pilot studies, and 1 was an uncontrolled trial. Only 10 studies explicitly declared the reference theoretical model. Considering their classification, 21 studies referred to the robotics motor control model, 12 to the self-organization model, 8 to the neuroanatomy model, and 4 to the ecological model. Our results showed that most of the rehabilitative interventions purposed in stroke rehabilitation have no clear theoretical bases on motor control and motor learning models. We suggest this is an issue that deserves attention when designing new experimental interventions in stroke rehabilitation.

Language and gesture neural correlates: A meta-analysis of functional magnetic resonance imaging studies.

BACKGROUND: Humans often use co-speech gestures to promote effective communication. Attention has been paid to the cortical areas engaged in the processing of co-speech gestures. AIMS: To investigate the neural network underpinned in the processing of co-speech gestures and to observe whether there is a relationship between areas involved in language and gesture processing. METHODS & PROCEDURES: We planned to include studies with neurotypical and/or stroke participants who underwent a bimodal task (i.e., processing of co-speech gestures with relative speech) and a unimodal task (i.e., speech or gesture alone) during a functional magnetic resonance imaging (fMRI) session. After a database search, abstract and full-text screening were conducted. Qualitative and quantitative data were extracted, and a meta-analysis was performed with the software GingerALE 3.0.2, performing contrast analyses of uni- and bimodal tasks. MAIN CONTRIBUTION: The database search produced 1024 records. After the screening process, 27 studies were included in the review. Data from 15 studies were quantitatively analysed through meta-analysis. Meta-analysis found three clusters with a significant activation of the left middle frontal gyrus and inferior frontal gyrus, and bilateral middle occipital gyrus and inferior temporal gyrus. CONCLUSIONS: There is a close link at the neural level for the semantic processing of auditory and visual information during communication. These findings encourage the integration of the use of co-speech gestures during aphasia treatment as a strategy to foster the possibility to communicate effectively for people with aphasia. WHAT THIS PAPER ADDS: What is already known on this subject Gestures are an integral part of human communication, and they may have a relationship at neural level with speech processing. What this paper adds to the existing knowledge During processing of bi- and unimodal communication, areas related to semantic processing and multimodal processing are activated, suggesting that there is a close link between co-speech gestures and spoken language at a neural level. What are the potential or actual clinical implications of this work? Knowledge of the functions related to gesture and speech processing neural networks will allow for the adoption of model-based neurorehabilitation programs to foster recovery from aphasia by strengthening the specific functions of these brain networks.

(Re)constructing identity following acquired brain injury: The complex journey of recovery after stroke.

INTRODUCTION: People with poststroke acquired brain injury (ABI) face a complex and often troubled identity reconstruction journey. The literature is rich with studies related to the psychological and neuropsychological components involved in rehabilitation, but it is lacking with respect to the investigation of the existential dimensions and the challenges associated with finding new senses and meanings for one's identity and future perspectives, body and interpersonal relationships. METHODS: The aim of this study is to investigate the narrative processes of identity reconstruction after brain damage. Through a qualitative approach, 30 autobiographical narratives about self, body and the relationships with others were collected and analyzed. Semistructured interviews were used for the data collection. Narrative and positioning analysis were applied. RESULTS: Four main positionings emerged: sanctioning a radical break with one's previous life; assuming a sense of salvation and compulsory as well as irreversible adaptation to the limitations associated with one's condition; feeling different and disabled; and considering new possibilities and active constructions of self-being in relationship with others. These results underline the narrative processes of construction of the injury and the identity and delineate possible resources and instruments to improve the clinical practice for health practitioners. They are also valuable for other professionals who deal with neurological services and rehabilitation, such as psychological counselling and support for persons who have experienced ABI and their families. PATIENT OR PUBLIC CONTRIBUTION: This work resulted from a close collaboration between two universities and a hospital neurological rehabilitation department in the Veneto Region (Northern Italy). Three associations of people with stroke and their families living in the same area contributed to designing the research on the basis of the needs expressed by their members with the aim to identify strategies and devices to be implemented in the public service to improve the care pathway. They also participated in the interpretation of the data.

Ambient assisted living systems for falls monitoring at home.

INTRODUCTION: Monitoring systems at home are critical in the event of a fall, and can range from standalone fall detection devices to activity recognition devices that aim to identify behaviors in which the user may be at risk of falling, or to detect falls in real-time and alert emergency personnel. AREAS COVERED: This review analyzes the current literature concerning the different devices available for home fall detection. EXPERT OPINION: Included studies highlight how fall detection at home is an important challenge both from a clinical-assistance point of view and from a technical-bioengineering point of view. There are wearable, non-wearable and hybrid systems that aim to detect falls that occur in the patient's home. In the near future, a greater probability of predicting falls is expected thanks to an improvement in technologies together with the prediction ability of machine learning algorithms. Fall prevention must involve the clinician with a person-centered approach, low cost and minimally invasive technologies able to evaluate the movement of patients and machine learning algorithms able to make an accurate prediction of the fall event.

Comparing kinematic asymmetry and lateral step-down test scores in healthy, chronic ankle instability, and patellofemoral pain syndrome female basketball players: a cross-sectional study.

We aimed to understand whether ankle dorsiflexion range of motion (ROM) and dynamic knee valgus (DKV) kinematic inter-limb asymmetries would be associated with the Lateral Step-Down Test (LSD) in basketball players with chronic ankle instability (CAI), patellofemoral pain (PFP) and healthy controls (HC). An observational cross-sectional study with a between-subject design was employed. Female basketball athletes with CAI (n = 20), PFP (n = 20) and HC (n = 20) were recruited. Ankle dorsiflexion-ROM, DKV angle during a single-limb squat, and LSD quality were measured bilaterally. The Asymmetry index (ASI) was calculated to identify between-limb percentage imbalances. The correlation matrix between the tasks was calculated. Ankle dorsiflexion-ROM was less in the CAI and PFP than in the HC group regardless of limb (p < 0.001). DKV angle was greater in the CAI and PFP than in the HC group bilaterally (p < 0.001). LSDs were similar between the PFP and CAI groups (p = 0.698) but worse than the HC group (p = 0.001). The ASI showed asymmetry across all tasks (p < 0.001), with the greatest asymmetry for the DKV angle. The correlation matrix between tasks on both limbs was significant (p < 0.05). Our findings suggest significant asymmetries in ankle dorsiflexion-ROM and frontal plane knee control are present in female basketball athletes with CAI and PFP, and thus, highlights need to evaluate and reduce limb asymmetries in these populations.

Stretch marks: a visible expression of connective's involvement in autism spectrum disorders.

In autism spectrum disorders (ASDs) in the pediatric population, skin manifestations are generally attributable to the concomitance of allergic forms or to accidental, self-inflicted or abusive lesions. However, clinical evidence has highlighted the presence of an increasing number of abdominal stretch marks, probably caused by the increase in the number of obesity cases in the pediatric population, in general, and therefore also among children with ASD. Stretch marks are often attributed to obesity, as they have an incidence of more than 50% in obese individuals. In the first part of this article we hypothesized that in addition to obesity there are other factors, such as a structural alteration on the skin in people with ASD, which can contribute/aggravate the phenomenon of stretch marks. Despite the high frequency with which stretch marks are found in children with ASD, this aspect has never been studied, the structure of the skin of children with ASD is not known. Furthermore, it is not known whether this structure is different from that of subjects without ASD. In the second part of the article, we hypothesized the mechanisms of the negative impact of simple abdominal stretch marks on the symptomatic picture of children with ASD. The presence of stretch marks, altered tactile perception, altered sensitivity to clothing fabrics can be a combination that influences development and determines negative consequences in the neurological picture of a child with ASD, as it is already known that the altered sensory perception in children with ASD contributes to the deterioration of social behavior. Furthermore, the presence of stretch marks may play a role in the postural and motor defects of children with ASD.

Clinical practice recommendations for management of lateropulsion after stroke determined by a Delphi expert panel.

OBJECTIVE: People exhibiting post-stroke lateropulsion actively push their body across the midline to the more affected side and/or resist weight shift toward the less affected side. Despite its prevalence and associated negative rehabilitation outcomes, no clinical practice guidelines exist for the rehabilitation of post-stroke lateropulsion. We aimed to develop consensus-based clinical practice recommendations for managing post-stroke lateropulsion using an international expert panel. DESIGN: This Delphi panel process conformed with Guidance on Conducting and Reporting Delphi Studies recommendations. PARTICIPANTS: Panel members had demonstrated clinical and/or scientific background in the rehabilitation of people with post-stroke lateropulsion. MAIN MEASURES: The process consisted of four electronic survey rounds. Round One consisted of 13 open questions. Subsequent rounds ascertained levels of agreement with statements derived from Round One. Consensus was defined a priori as ≥75% agreement (agree or strongly agree), or ≥70% agreement after excluding 'unsure' responses. RESULTS: Twenty participants completed all four rounds. Consensus was achieved regarding a total of 119 recommendations for rehabilitation approaches and considerations for rehabilitation delivery, positioning, managing fear of falling and fatigue, optimal therapy dose, and discharge planning. Statements for which 'some agreement' (50%-74% agreement) was achieved and those for which recommendations remain to be clarified were recorded. CONCLUSIONS: These recommendations build on existing evidence to guide the selection of interventions for post-stroke lateropulsion. Future research is required to elaborate specific rehabilitation strategies, consider the impact of additional cognitive and perceptual impairments, describe positioning options, and detail optimal therapy dose for people with lateropulsion.

Placebo effect on gait: a way to reduce the dual-task cost in older adults.

The ability to perform two tasks simultaneously is essential for daily activities. In older adults, this ability is markedly reduced, as evidenced by the dual-task cost on gait. Preliminary evidences indicate that the dual-task cost can be influenced by different types of manipulations. Here, we explored the effectiveness of a new approach to reduce the dual-task cost, based on the placebo effect, a psychobiological phenomenon whereby a positive outcome follows the administration of an inert device thought to be effective. Thirty-five healthy older adults were asked to walk on a sensorized carpet (single-task condition) and to walk while counting backward (dual-task condition) in two sessions (pre-test and post-test). A placebo group, randomly selected, underwent sham transcranial direct current stimulation over the supraorbital areas between sessions, along with information about its positive effects on concentration and attention. A control group did not receive any intervention between sessions. The dual-task cost was significantly reduced in the placebo group at the post-test session compared to the pre-test for several gait parameters (Cohen's d > 1.43). At the post-test session, the dual-task cost was also lower in the placebo group than in the control group (d > 0.73). Cognitive (number of subtractions and number of errors) and subjective (perceived mental fatigability) variables remained stable across sessions. The reduced dual-task cost in the placebo group could indicate the ability to re-establish the allocation of attentional resources between tasks. These findings could contribute to the development of cognitive strategies that leverage positive expectations to boost motor control in older adults.

Neck Pain in Fibromyalgia: Treatment with Exercise and Mesotherapy.

BACKGROUND AND OBJECTIVES: Fibromyalgia is a very common musculoskeletal disease. The purpose of this study is to assess, on a population of fibromyalgic patients, the clinical efficacy of antalgic mesotherapy with diclofenac and thiocolchicoside in the treatment of cervical pain reduction for improvement of the functional capacity and quality of life of these patients. MATERIALS AND METHODS: We conducted an observational study of 78 fibromyalgia patients recruited using our hospital database. Based on the different types of treatment received, the patients were divided into two groups: the treatment group (TG), who received antalgic mesotherapy with diclofenac, thiococolchicoside, and mepivacaina; and the placebo group (PG), who received mesotherapy with sodium chloride solution. Patients in both groups also received the same rehabilitation protocol of 20 sessions. The primary outcome evaluated was the extent of pain. The secondary outcomes were the functional capacity and quality of life. RESULTS: Pain improved both in the treatment group (7.4 ± 1.2 vs. 5.1 ± 1.1; p < 0.05) and placebo group (7.5 ± 1.4 vs. 6.1 ± 1.6; p < 0.05). The treatment group, compared to the placebo group, also showed significant statistical improvements in functional capacity (NDI: 35.6 ± 5.23 vs. 19.3 ± 3.41; p < 0.05) and quality of life (SF-12: 18.3 ± 4.11 vs. 33.1 ± 2.41; p < 0.05). CONCLUSIONS: Mesotherapy treatment with diclofenac and thiocolchicoside is a safe and effective procedure in the management of neck pain in fibromyalgia patients in the short term in terms of pain reduction, functional recovery and quality of life.

Long-Term Spasticity Management in Post-Stroke Patients: Issues and Possible Actions-A Systematic Review with an Italian Expert Opinion.

Spasticity is a well-known motor dysfunction occurring after a stroke. A group of Italian physicians' experts in treating post-stroke spasticity (PSS) reviewed the current scientific evidence concerning the state-of-the-art clinical management of PSS management and the appropriate use of botulinum toxin, aiming to identify issues, possible actions, and effective management of the patient affected by spasticity. The participants were clinicians specifically selected to cover the range of multidisciplinary clinical and research expertise needed to diagnose and manage PSS. When evidence was not available, the panel discussed and agreed on the best way to manage and treat PSS. To address the barriers identified, the panel provides a series of consensus recommendations. This systematic review provides a focused guide in the evaluation and management of patients with PSS and its complications. The recommendations reached by this panel of experts should be used by less-experienced doctors in real life and should be used as a guide on how to best use botulinum toxin injection in treating spasticity after a stroke.

Dual tasking affects gait performance but not automaticity in functional gait disorders: A new diagnostic biomarker.

INTRODUCTION: Functional gait disorders (FGDs) are disabling symptoms of Functional Motor Disorders. Clinical observations show improvement with distraction suggesting an association with higher-level control mechanisms. Dual tasking is a valuable tool for exploring the interplay between gait and cognition. Our research question was: how do different dual task paradigms shape spatio-temporal gait parameters in FGDs?. METHODS: In all, 29 patients with FGDs (age 43.48 ± 15.42 years; female 75%) and 49 healthy controls (age 43.33 ± 15.41 years; female 62%) underwent spatio-temporal gait analysis during a single task and during performance on a motor, a cognitive, and a visual-fixation dual-task. The dual-task effect was a measure of interference of the concurrent task on gait speed, stride length (a measure of gait performance), and stride time variability (a measure of automaticity and steadiness). RESULTS: Overall lower gait speed, shorter stride length, and higher stride time variability were noted in FGDs compared to healthy controls (for all, p < 0.019). The was a significant effect of group and Task × Group interaction for the dual-task effect on gait speed (p = 0.023) and stride length (p = 0.01) but not for stride time variability. CONCLUSION: Poorer gait performance and less automaticity and steadiness were noted in FGDs. However, dual tasking affected gait performance but, unlike different neurological diseases, not automaticity and steadiness compared to controls. Our findings shed light on higher-level gait control mechanisms in FGDs and suggest stride time variability could be a diagnostic and prognostic biomarker.

Management Of Spastic Equinovarus Foot in Children with Cerebral Palsy: An Evaluation of Anatomical Landmarks for Selective Nerve Blocks of the Tibial Nerve Motor Branches.

OBJECTIVE: To define the anatomical landmarks of tibial motor nerve branches for selective motor nerve blocks of the gastrocnemii,  soleus and tibialis posterior muscles in the management of spastic equinovarus foot. DESIGN: Observational study. PATIENTS: Twenty-four children with cerebral palsy with spastic equinovarus foot. METHODS: Considering the affected leg length, motor nerve branches to the gastrocnemii, soleus and tibialis posterior muscles were tracked using ultrasonography, and located in the space (vertical, horizontal, deep) according to the position of fibular head (proximal/distal) and a virtual line from the middle of popliteal fossa to the Achilles tendon insertion (medial/lateral). RESULTS: Location of motor branches was defined as percentage of the affected leg length. Mean coordinates were: for the gastrocnemius medialis 2.5 ± 1.2% vertical (proximal), 1.0 ± 0.7% horizontal (medial), 1.5 ± 0.4% deep; for the gastrocnemius lateralis 2.3 ± 1.4% vertical (proximal), 1.1 ± 0.9% horizontal (lateral), 1.6 ± 0.4% deep; for the soleus 2.1 ± 0.9% vertical (distal), 0.9 ± 0.7% horizontal (lateral), 2.2 ± 0.6% deep; for the tibialis posterior 2.6 ± 1.2% vertical (distal), 1.3 ± 1.1% horizontal (lateral), 3.0 ± 0.7% deep. CONCLUSION: These findings may help the identification of tibial motor nerve branches to perform selective nerve blocks in patients with cerebral palsy with spastic equinovarus foot.

The role of feedback in the robotic-assisted upper limb rehabilitation in people with multiple sclerosis: a systematic review.

INTRODUCTION: Robotic-assisted upper limb rehabilitation might improve upper limb recovery in people with multiple sclerosis (PwMS) with moderate-to-severe disability. In the few existing studies, the training effects have been related to the type of intervention, if intensive, repetitive, or task-oriented training might promote neuroplasticity and recovery. Notably, most of these devices operate within a serious game context providing different feedback. Since feedback is a key component of motor control and thus involved in motor and cognitive rehabilitation, clinicians cannot desist from considering the potential contribution of feedback in the upper limb robot-assisted rehabilitation effects. AREA COVERED: In this systematic review, we reported the rehabilitation protocols used in the robot-assisted upper limb training in PwMS to provide state-of-the-art on the role of feedback in robotic-assisted Upper Limb rehabilitation. PubMed, the Cochrane Library, and the Physiotherapy Evidence Database databases were systematically searched from inception to March 2022. After a literature search, the classification systems for feedback and the serious game were applied. EXPERT OPINION: There is a need for sharing standard definitions and components of feedback and serious game in technologically assisted upper limb rehabilitation. Indeed, improving these aspects might further improve the effectiveness of such training in the management of PwMS.

eXplainable AI Allows Predicting Upper Limb Rehabilitation Outcomes in Sub-Acute Stroke Patients.

While stroke is one of the leading causes of disability, the prediction of upper limb (UL) functional recovery following rehabilitation is still unsatisfactory, hampered by the clinical complexity of post-stroke impairment. Predictive models leading to accurate estimates while revealing which features contribute most to the predictions are the key to unveil the mechanisms subserving the post-intervention recovery, prompting a new focus on individualized treatments and precision medicine in stroke. Machine learning (ML) and explainable artificial intelligence (XAI) are emerging as the enabling technology in different fields, being promising tools also in clinics. In this study, we had the twofold goal of evaluating whether ML can allow deriving accurate predictions of UL recovery in sub-acute patients, and disentangling the contribution of the variables shaping the outcomes. To do so, Random Forest equipped with four XAI methods was applied to interpret the results and assess the feature relevance and their consensus. Our results revealed increased performance when using ML compared to conventional statistical approaches. Moreover, the features deemed as the most relevant were concordant across the XAI methods, suggesting good stability of the results. In particular, the baseline motor impairment as measured by simple clinical scales had the largest impact, as expected. Our findings highlight the core role of ML not only for accurately predicting the individual outcome scores after rehabilitation, but also for making ML results interpretable when associated to XAI methods. This provides clinicians with robust predictions and reliable explanations that are key factors in therapeutic planning/monitoring of stroke patients.

Short-wave diathermy for spastic equinus foot in chronic stroke patients: a proof-of-concept pilot study.

BACKGROUND: Physical modalities may be useful to manage poststroke spasticity. Shortwave diathermy has been demonstrated to improve extensibility of the myotendinous tissue. Spasticity may alter morphology of the muscle and its elastic properties. Our main aim was to evaluate the effects of shortwave diathermy on spastic equinus foot in stroke patients. METHODS: Ten chronic stroke patients with spastic equinus foot received 10 shortwave diathermy sessions, 5 days/week for 2 consecutive weeks to the spastic calf muscles. Clinical (modified Ashworth Scale and ankle dorsiflexion passive range of motion) and ultrasound (spastic gastrocnemius muscle echo intensity and hardness percentage measured by sonoelastography) evaluation was done before, after treatment, and at two weeks of follow-up. RESULTS: A significant difference in calf muscle spasticity (P=0.004), ankle passive range of motion (P=0.014), and spastic gastrocnemius muscle hardness percentage (P=0.004) was found after treatment. A significant difference in calf muscle spasticity (P=0.004) was found also at the follow-up evaluation. CONCLUSIONS: Our preliminary findings support the hypothesis that shortwave diathermy might improve calf muscle tone, ankle passive range of motion, and gastrocnemius muscle elasticity in chronic stroke patients with spastic equinus. This might be due to the deep thermal effects coupled with the rheological direct action of shortwave diathermy on spastic muscles.

Effect of Upper Limb Motor Rehabilitation on Cognition in Parkinson's Disease: An Observational Study.

Parkinson's disease is characterized by motor and cognitive deficits that usually have an impact on quality of life and independence. To reduce impairment, various rehabilitation programs have been proposed, but their effects on both cognitive and motor aspects have not been systematically investigated. Furthermore, most intervention is focused on lower limb treatment rather than upper limbs. In the present study, we investigated the effect of 3-week upper limb vibratory stimulation training on cognitive functioning in 20 individuals with Parkinson's disease. We analyzed cognitive (Montreal Cognitive Assessment, Trial Making Test, Digit Symbol, Digit Span Forward and Backward and Alertness) and motor performance (Unified Parkinson's Disease Rating Scale-part III; Disability of the Arm, Shoulder and Hand Questionnaire) before treatment, at the end of treatment and one month post treatment. After rehabilitation, a statistically significant improvement was observed in terms of global cognitive status, attention, global motor functioning and disability. The results suggest an impact of upper limb motor rehabilitation on cognition in Parkinson's disease. Future studies on neuromotor interventions should investigate their effects on cognitive functioning to improve understanding of cognitive motor interaction in Parkinson's disease.

IncobotulinumtoxinA Injection for Treating Children with Idiopathic Toe Walking: A Retrospective Efficacy and Safety Study.

There is no gold-standard treatment for idiopathic toe walking (ITW). Some previous evidence suggested that botulinum neurotoxin-A injection might improve ITW. This is a single-center retrospective study on children with ITW treated with incobotulinumtoxinA injection in the gastrocnemius medialis/lateralis muscles. We screened the charts of 97 ITW children treated with incobotulinumtoxinA (January 2019-December 2021), and the data of 28 of them, who satisfied the inclusion/exclusion criteria, were analyzed. The maximal passive ankle dorsiflexion (knee extended) was assessed at three time points, i.e., immediately before incobotulinumtoxinA injection (T0), after incobotulinumtoxinA injection during the timeframe of its effect (T1), and at follow-up, when the effect was expected to disappear (T2). The maximal passive ankle dorsiflexion was improved by incobotulinumtoxinA injection, and the effect lasted up to 6 months in some children. No adverse effects were reported to incobotulinumtoxinA injections. The treatment with incobotulinumtoxinA might improve the maximal passive ankle dorsiflexion and is safe and well-tolerated in ITW with a longer-than-expected effect in comparison to cerebral palsy. These results may offer ground to future randomized controlled trials and studies assessing the effect of BoNT-A in combination with other non-invasive approaches and exercise programs in children with ITW.
